LATHE FOR WINDING ARMATU'RES.

SPECIFICATION forming part of Letters Patent No. 415,805, dated November26, 1889.

Application filed July 5, 1889- Serial No. 316,519. (No model.)

To all whom it may concern.- so that the latter may be applied to saidhead Be it known that I, WARREN S. BELDING, a between theclamping-posts, as hereinafter citizen of the United States, residing atEndescribed. The portion of said head oppoglewood, in the county of Cookand State of site the sleeve D and the shaft B has an Illinois, haveinvented certain new and useoblique concave face d conforming to the 55ful Improvements in Lathes for \Vinding Arsurface of a segment of acylinder about matures; and I do hereby declare the followequal to thediameter of the armature to be ing to be a full, clear, and exactdescription Wound, the axis of such segment being reof the invention,such as will-enable others garded as at right angles to and away fromskilled in the art to which it appertains to the produced axis of theshaft- B. 60 make and use the same, reference being had E is a sectionof an armature to be wound. to the accompanying drawings, and to lettersThe degree of obliquity of the face (I with of reference marked thereon,which form a reference to the produced axis' of the shaft partof thisspecification.

Tothis end I have devised a said bobbin-space and the produced axis ofchuck for holding said sections, as hereinafter said shaft are made tocoincide. It is obvidescribed, and specified in the claims. ous that ifthe shaftB is now rotated the said 75 In the accompanying drawings,Figure 1 is bobbin-space of the section E will be rotated a sideelevation of a lathe embodying my imaccurately upon its own axis, andthe wire 6' provement. Fig. 2 is apartial side elevation may be woundupon said bobbin-space as of the same. Fig. 3 is a section in line 00a:of upon a reel or spool. Since the face (1 and 0 Fig. 4. Fig.4 is ageneral view of the chuck. the outer face of the armature-section are 80In said drawings, A A are standards havsubstantiallyalike, it followsthat the secing at their upper ends bearings A, in which tion E may nowbe moved upon said face sufis supported a shaft B. C is a crankapficiently to bring another bobbin-space 6 into plied to one end ofsaid shaft for rotating the produced axis of the shaft B in front of thelatter by hand-power. Said shaft may, said head, so that said otherbobbin-space 85 however, be driven by other power. The opmay be wound aswas the previous one. Thus posite end of the shaft B extends beyond onebobbin-space after another may bewound its bearing to receive the chuckD. Said until the entire section is completed. While chuck consists ofthe sleeve D, the head D the winding is performed the section must bethe clamping-bar D and the clamping-posts firmly secured to the head.For this purpose 90 D The sleeve D is fitted over the shaft B, I haveprovided the clamping-bar D and the and secured immovably thereto by oneor clamping-posts D Said clamping-bar is arnlore screws (1 or otherwise,so that said ranged to lie across the inner face of the secchuck willrotate with the shaft B. The head tion E, parallel to the axis of thelatter, and

I claim as my invention 1. In a lathe for Winding the sections ofarmatures, the combination, with the shaft of such lathe, of a head Dhaving the oblique face (V, and means for clamping: thearmature-sections to said head, substantially as shown and described.

2. In a lathe for winding the sections of armatures, the combination,with the shaft of such lathe, of a head D having the oblique face 01 aclamping-bar D and clampingposts D joining said clamping-bar to saidhead,substanti ally as shown and described.

3. I11 a lathe for winding armature-sections, the combination, with theshaft of said lathe, of a chuck D, consisting of a sleeve D, head Dprovided with the oblique face 01 clamping-bar D and clamping-posts Djoining said clamping-bar to said head, substantially as shown anddescribed.

, 4. In a lathe for winding armature-sections, the combination, with theshaft of such lathe, of a head D provided with the oblique face 61clamping-bar D and clamping-posts D consisting of screw-bolts extendingthrough the ends of said clamping-bar and threaded into the ends of saidhead, substantially as shown and described. 7

In testimony whereof I affix my signature, in presence of two witnesses,this 25th day of June, 1889.
